Virtualized VirtualBox PC hangs during boot

Dear All,
I acquired the disks of several PCs using ftkimager obtaining compressed E01 files.
I converted each E01 file into vdi format and created a VirtualBox virtual machine for each device.

Some virtualized PCs hung during boot when the OS loads the driver CLASSPNP.SYS.

Probably there is a wrong driver that should be replaced ore removed.

The operative system is Windows 7 Professional SP1.
I did boot using a Windows 7 rescue CD, but I obtained an error when trying to repair the operative system.

Which actions do you recommends?
The PCs use UEFI and not MBR.

Best Regards
Andrea Liguoro
